Question

Y = 6 - 31
y =- 7x + 21

Answer 1

Explanation:

its is y=67 or it might be y=7 i

Answer 2

Solve by elimination.

multiply the lower equation by negative 1.

-y=7x-21

-y+y=o

new equation is

7x+6-52=0

6-52 is -46

-7x=-46

divide by -7

x=6.57...

plug it back in

y= 7(6.57)+21

7*6.57= 46

y=46+21

y=67

(might be wrong, I tried)
